This document discusses how to build audiences in real time by microtargeting consumers across hundreds of digital audiences. It explains how to map a consumer target like "Cheryl" to various digital audiences based on her interests and how those audiences can then be combined and tested to drive lower costs and higher engagement. Top performing audience combinations are identified and influencers within those interest areas are mapped to help connect messaging to the right audiences.
